Polyhedron Model by Martin Berman, Gyroelongated Triangular Cupola

The top of this model is an equilateral triangle and the bottom a regular hexagon. Above the hexagon is a ring of twelve equilateral triangles in alternating directions. Above these triangles is a row of three equilateral triangles alternating with three squares. The model has a total of sixteen equilateral triangles, three squares, and one regular hexagon.
